=====================================================================

In this FTP, we don't have an access to get the list of files/folders for this user.
With out verifying/getting the list, just we need to upload a file in ftp's root folder. Please help me how I can achieve this. We can put the file using Windows File Explorer.
Please help me to resolve this error.

Thanks & Regards

Hello,

the Ftp.PutFile method is suitable for this purpose. it does not perform any listing prior to the file upload.

Are you able to upload the file to the FTP server root with the short code below?

Ftp client = new Ftp();
ftp.LogWriter = new Rebex.FileLogWriter(@"C:\logs\ftp-log.txt", Rebex.LogLevel.Debug);
client.Connect("ftp2.ftccc.net");
client.Login("ftp2.ftccc.net", "your-password");

// upload the local file to FTP server's root
client.PutFile(@"C:\data\SALCINV_20150915152617.AMI", "/SALCINV_20150915152617.AMI");
client.Disconnect();

Please give it a try and let me know whether it works.

Hello,

I have tried with the same code which you provided. Issue is still reproducing. See below error log.

================================================================

Now we are able to upload the file from both FileZilla and Windows File Explorer.
We are having this issue with only Rebex PutFile method.

Please help me to resolve this error.

Answer 2

This is really strange error message. Perhaps the server doesn't allow write access to the FTP root folder, or it doesn't like absolute paths. Can you please try the following code?

The code will upload the file into current working directory. You can determine what is your current working directory using the client.GetCurrentDirectory() method. To change working directory use the client.ChangeDirectory() method.

If it still doesn't work. Please send us FileZilla log for comparison.

Ftp client = new Ftp();
client.LogWriter = new Rebex.FileLogWriter(@"C:\logs\ftp-log.txt", Rebex.LogLevel.Debug);
client.Connect("ftp2.ftccc.net");
client.Login("user-name", "user-password");

// change working directory if needed
//client.ChangeDirectory("/");

// upload the local file to current working directory 
// at the FTP server
client.PutFile(@"C:\data\test123.txt", "test123.txt");
client.Disconnect();

May I know how the FileZilla and Windows File Explorer are handling this?

If we know the generic fix, it is very useful for other FTPs.

I don't know what you mean by generic fix... If your requirement is upload to home directory, I already provided a simple code to achieve this with Rebex which will work with any FTP server.  If apart from this, you will also need to upload to some other directories (e.g. to "non-home directories") then you have to know what is the target directory for each FTP server. And you will have to have a parameter / config value / GUI pick in your program that you will use to determine where exactly you need to upload.

For sample implementation of a GUI FTP client, please check our Ftp WinformClient sample (http://www.rebex.net/sample/ftp-winform-client-classic/). The sample source code comes as a part of your Rebex FTP/SSL package.

And by the way, could you please share your order ID or the email that you used to buy your Rebex FTP license? Unfortunatelly, I was unable to find your order in our system.

Thank you.

We have a different email id which has Rebex license. Unfortunately we missed the password. So we created an anonymous user in Rebex and created this ticket.

---

Ok, no problem, but what is the registered email? You can send it to us privately to support@rebex.net and I will associate the forum account with your license then. Thank you.
